FDA Cracks Down on Some Stem Cell Clinics for Unproven Treatments
The FDA is still working to protect the U.S. population from medical chicanery while some of the federal government is wasting money, frittering away time, and trying to harm people. The new target for the agency is stem cell clinics and purveyors of"regenerative medicine" (see:FDA cracks down on stem-cell clinics, including one using smallpox vaccine in cancer patients). Below is an excerpt from the article:The Food and Drug Administration...announced a crackdown on stem-cell clinics offering unproven and potentially dangerous treatments, including an operation in California that the agency said was using the sm...

Premature origin of LCX from “ mid-shaft ” of left main . . . with no bifurcation !
Left main bifurcates into two , that’s the classical anatomical behavior of LCA. (Or it trifurcates) When left main divides , it tends to share its diameter between its two siblings LAD and LCX with considerable whims and fancies.(Though Finet* et all thought it has a working rule !) * From Biomedical Engineering, Cardiovascular Hospital and Claude Bernard University France
Now , have a look at this , its a rare example of how a left main might Ignore the rule of bifurcation just like that !
Left main simply continues as left main* after giving off a casual side branch from mid left main shaft .Yes , Its ...

China launches brain-imaging factory (Nature):
“Neuroscientists who painstakingly map the twists and turns of neural circuitry through the brain are about to see their field expand to an industrial scale. A huge facility set to open in Suzhou, China, next month should transform high-resolution brain mapping, its developers say.
Where typical laboratories might use one or two brain-imaging systems, the new facility boasts 50 automated machines that can rapidly slice up a mouse brain, snap high-de...

Ultrasound Controls Delivery of Local Anesthetic Just When and Where It Hurts
Localized pain caused by disease, injury, or surgery can be hard to control, and it leads too many people to use opioids. Though there are electronic and physical methods that can help manage some pain, these are typically only marginally effective and usually only work on targets close to the skin. Now a team from Boston Children’s Hospital has come up with a way to use ultrasound to trigger the release of an anesthetic previously injected into the affected region.
The anesthetic is encapsulated within liposomes, tiny sacks made of lipids derived from cellular membranes. The walls of the liposomes are also seeded wi...

New Joint Implant Coating to Prevent Bacterial Infections
Much too often artificial joints become infected after implantation and revision procedures are common. Antibiotic-enriched bone cement is often positioned within an infected joint after removing the implant and allowed to do its thing for a number of weeks before a new implant is introduced. The problem is that the bone cement is limited in its ability to kill nearby bacteria and using it requires two separate revision surgeries: explantation of the original implant and implantation of bone cement, followed by implantation of the replacement joint.
Now a team at Massachusetts General Hospital has come up with a polymer ...

Tough Hydrogel Swells in Stomach for Drug Delivery
In this study, which was recently published in Nature Communications, researchers designed tough hydrogels that can be loaded with a drug. When hydrated, the hydrogels exist as a tough Jell-o-like material. When dehydrated, they are small enough to be swallowed comfortably. However, upon absorbing fluid in the stomach they swell, becoming too large to pass through the stomach into the intestine. The result is that the gels reside in the stomach for up to 9 days, and release a drug in a sustained way before passing through the body harmlessly.
To withstand the compression forces in the stomach, the hydrogels are really toug...

Software Models Liver ’s Movement to Guide Surgeons to Target Tumors
Squishy viscera, such as the liver, can change their shape significantly from the time a CT scan is taken that spots a tumor to when it’s excised during surgery. Various tags have been developed that can be tacked onto tissue in order to use as a point to calibrate against, but this approach still doesn’t quite achieve the desired precision. Researchers at Vanderbilt University have now developed an algorithmic approach that correlates CT scan data with how the soft tissue is manipulated during surgery, guiding the surgeon to the correct location of the target tumor. The software models the movement of the or...

Light-Sheet Microscopy Images Tumor Margins Intraoperatively to Guarantee Full Tumor Removal
Surgical tumor removal, particularly within the breasts, suffers from imprecision related to identifying the margins of where the tumor is. That’s because tumors are often indistinguishable from healthy tissue until they’re visualized and analyzed by pathologists using laboratory microscopes. The time it takes to confirm that sampled tissue is clear of cancerous cells takes longer than a person can stay open and under anesthesia, so the final word usually comes in only after the patient has been stitched up and so too often leads to revision surgeries.
Researchers at the University of Washington have now devel...

Neurosurgical Simulator for Real-Time Guidance of Interventional Instruments
The brain is a difficult organ to operate on in part due to its jelly-like consistency and because what’s below the surface is not visible, save for pre-op imaging. Because it is so soft and gelatinous, the brain compresses as soon as an instrument touches it, which affects the location of the target and how easily one can get to it. While pre-op imaging can give a good idea of where the surgeon is trying to get to, once the surgery starts the precision of the assumed location is compromised and requires doctors to rely a great deal on their intuition and experience.

Microchip for Sorting and Identifying Large Numbers of Circulating Tumor Cells
Detection and classification of circulating tumor cells (CTCs) may soon become a common method for screening for multiple types of cancer. Fluorescence-activated cell sorting (FACS) is popular one technique for spotting CTCs, but it’s limited because the number of available dye colors is small and because for CTCs of certain cancers there aren’t any markers at all. Since few markers exist, the signal is often vague because multiple cell types end up being collected into the same container.

Pocket Colposcope for Cervical Cancer Screening by Anyone Anywhere
Scientists at Duke University have developed a handheld colposcope that can be used for cervical screening. The slender wand can be attached to a smartphone or laptop to display images of the cervix.
At present, detecting cervical cancer requires specialized equipment. Healthcare professionals use a device called a speculum to spread the vagina and an expensive colposcope, which is a telescopic magnifying device and camera, to look at the cervix for signs of cancer. This expensive equipment means that cervical cancer detection is much lower than it should be in low-resource settings around the world.
Cervical cancer is the...

Soon We Might Get a Real-Time, Panoramic View of the Human Body ’s Insides
What if you could view the insides of the human body in high-resolution? A group of researchers at Duke University and California Institute of Technology have created technology that allows us to examine the body inside-out.The Optical Imaging Laboratory has developed a technique called single-impulse photoacoustic computed tomography, or SIP-PACT, that can view up to five centimeters into biological tissue with “sub-millimeter-level resolution” while enabling functional information from the conventional optical microscopy.MRI takes seconds to minutes to generate an image, and over time, x-rays can transmit too much ra...
